Question

A $20 shirt is 40% off. Your trying to figure out if you have enough cash for this. How much is the final price of the shirt?

Answer 1

original price: $20

discount: 40%

`20\cdot0.4=8`

Discount is $8

Final price:

`20-8=12`

The final price is $12

The percentage you are actually paying is 100% - 40% = 60%

The equation that describes this problem is:

`\begin{gathered} A=P\cdot((100-d))/(100) \\ A=20\cdot(100-40)/(100)=12 \end{gathered}`

Where A is the actual price, P is the original price and d is the discount.
